如果双用途软件包默认为每台机器，则按用户安装始终需要管理员权限

Question

我正在尝试使用 WiX 创建一个双重用途的 MSI 文件。我已按照WixUI_Advanced 的说明以及Single Package Authoring 的说明进行操作。当我默认默认按用户安装 (MSIINSTALLPERUSER = 1) 并允许用户选择按机器安装时，这似乎工作正常。但是，将其默认设置为每台机器安装（MSIINSTALLPERUSER 为空）总是会导致 UAC 提示，即使用户选择了每用户安装也是如此。每用户安装只是将单个文件写入非管理员目录，绝对不需要提升权限。

我还尝试关注this guide，每个人似乎都在使用它来使用 WiX 进行单包创作，但结果完全相同。如果每台机器是默认设置并选择了每用户，则会出现 UAC 提示，但如果默认设置为每用户并选择每用户，则不会出现 UAC 提示。

查看安装日志，我看到以下条目：

Answer 1

根据安装日志，我尝试从 this guide 重新引入修改后的 WixUI 文件中替换的行，这会更新 ALLUSERS 属性，因为似乎这被设置为每个用户安装的值 1将解释 UAC 提示。俄罗斯博客和原始 WixUI_Advanced 中的以下几行似乎确实有效。

<Publish Dialog="InstallScopeDlg" Control="Next" Property="ALLUSERS" Value="{}" Order="2">
    WixAppFolder = "WixPerUserFolder"
</Publish>
<Publish Dialog="InstallScopeDlg" Control="Next" Property="ALLUSERS" Value="1" Order="3">
    WixAppFolder = "WixPerMachineFolder"
</Publish>
<Publish Dialog="InstallScopeDlg" Control="Next" Property="MSIINSTALLPERUSER" Value="1" Order="3">
    WixAppFolder = "WixPerUserFolder"
</Publish>
<Publish Dialog="InstallScopeDlg" Control="Next" Property="MSIINSTALLPERUSER" Value="{}" Order="2">
    WixAppFolder = "WixPerMachineFolder"
</Publish>

似乎 both ALLUSERS 和 MSIINSTALLPERUSER 需要根据用户的选择进行设置，以在默认情况下每台机器安装时允许在没有管理员权限的情况下进行安装。但是，我无法在网上找到其他任何地方来确认我的发现。
